Jackson shimmied all the way to the final in 2005 but boxer Calzaghe displayed rather less skill as he made an early exit last year.

Fellow Welshman Gethin Jones came third in the 2007 show.

But Henson, 28, found himself back in the rugby spotlight as he was today unveiled wearing the new Wales jersey in a Welsh Rugby Union marketing campaign.

The WRU says the marketing campaign includes "stars of past and present". But as Henson remains on indefinite unpaid leave from rugby it is not clear which category the Ospreys centre fits into.

And Wales centre Jamie Roberts joined the debate on Henson promoting the national team's new kit.

Posting on his Twitter account, Roberts asked: "Is this an insult to current welsh International players....wonder what the welsh public will think?!" Roberts then links to a 50ft-high picture of Henson on the Millennium Stadium.

Speaking earlier this week on Radio Wales' Good Morning Wales, Ospreys director of rugby Scott Johnson said: "If Gavin said that he hasn't said that to me.

"Since I've been back in Wales I have had one conversation with Gavin Henson."

But Henson has the backing of at least one teammate after Ospreys and Wales star Shane Williams said he would be voting for Gavin - though he called into question his dancefloor skills.

"I'm sure I'll have a cheeky vote for him when he does actually start showing us his stuff on the dancefloor.

'Puffing'

"I'm not sure how good he's going to be to be honest with you because having spent a lot of time with Gavin he couldn't really dance very much before so unless he been practising quite profusely, we'll have to wait and see."

Former MP Ann Widdecombe was also revealed in the line up for this year's Strictly Come Dancing.

Speaking on BBC Radio Wales, she said: "I think Gavin is utterly charming.

"Like me he was a bit bewildered at first but of course he can lift the ladies so easily.

"Whereas everybody else is puffing he can do it with one hand almost."
